Terrified, any tips?

It took 3years of TTC and 3 early miscarriages to get where We are. I’m roughly 4/5weeks pregnant (very early) and I am terrified of miscarrying again. I went to see the nurse and she didn’t seem overly concerned with our MC history and referred me to the midwife team, but I constantly feel on edge.

I’ve been crampy since 9dpo but they are slowly decreasing - and I am very emotional - I cry at the drop of a hat.

I was just wondering if anyone has any tips to quell the anxiety please? My hubby is trying to stay positive by planning where the crib will go and what pram-/car seat he wants to go look at, but I feel like it’s all a jinx :(
